Is common peony safe for cats and dogs?
Mildly. The ASPCA flags common peony as mildly toxic to cats and dogs — a chewing pet gets oral irritation and drooling rather than a medical emergency, but it is still worth a high shelf. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Paeonia officinalis is listed by the ASPCA as toxic to dogs and cats, causing gastrointestinal upset (vomiting, diarrhea) if plant material is ingested. The toxic principle is paeonol. All parts are considered toxic, though serious systemic effects are uncommon.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |
